'Teen Mom 3': Alex And Matt Get Into An Intense Fight (VIDEO)

Alex already had plenty of trust issues with her baby daddy Matt, considering his past. He was now fresh out of rehab on "Teen Mom 3," but she was almost immediately suspicious that he'd gone back to using. Regardless, Alex's mom, Wendy, let Matt move in with them so he could help raise his daughter.

But then, Alex found out that Matt was talking to another girl behind her back, and was neglecting their daughter to hang out with friends. It all became too much for her to handle and she confronted him. “Get your f*cking child and take care of her!” Alex shouted. In response, Matt flipped her off.

As the argument escalated, Matt started getting confrontational himself. Taking off his sweatshirt -- because guys always take off their shirt when they're getting ready to fight for some reason -- Matt goaded Alex, saying, "What the f*ck you gonna do? Huh? The f*ck's up? F*ck's up? Do something, b*tch! Hit me! Hit me!”

Ultimately, Wendy helped pull the two of them apart. After seeing this display, she decided to kick Matt out of her home. She also told her daughter to stop seeing Matt altogether.

Hollywood Life's Emily Longeretta was definitely feeling uncomfortable as things escalated. "While both continued the argument, Matt crossed a line by getting in Alex’s face. The two called each other about every curse word in the book," she wrote. "However, Alex admitted that she doesn’t know if she can [stop seeing Matt] because she wants Arabella to have a father.”
